The winter It is a hard stage in these valleys and moors. Only in the area of the juniper forest that looms large in the area northeast, to Torremocha de Ayllón, there is more movement given the good supply of fruit that gives juniper forest winter birds. Good sides of thrushs, Common blackbirds, magpies and other birds you can be observed here. At this stage also the Griffon vulture and the Eurasian eagle owl They begin their breeding period.
February it is the month in which, some timid start to notice changes in the environment with the appearance of some Wood larks in any of the open forests of the region, or Crag martins in the gorges. In the riparian forest of the river Eurasian nuthatches -recent settlers- they are the most active, although there are Great spotted woodpecker and European green woodpeckers.
March and we anticipate the arrival of spring. Wintering birds are leaving the area and they come in other, like the European serin and the Black redstart in these lands behave as partial migratory species. If there is a characteristic bird of the canyon is the Egyptian vulture. Three couples by different cut are distributed to the least and when they arrive in march, being seen standing on the rocky areas without major problems.
These also rocky areas are being occupied by birds that have gone back and forth in Autumn Winter but what, at the call of reproduction, they reoccupy holes and cracks: the Red-billed chough and Western jackdaw, the latter increasingly scarce. Perhaps the decline in the sheep population has to do with this other observable part rarefaction elsewhere in Soria. The Ravens they are the lords of the canyon, chasing and harassing even the Golden Eagle if it enters its territory. Also some Peregrine falcon you can still be, little, gorges.
In May and June we can observe Blue rock thrush, Rock sparrow, Stock dove, Common kestrel and Rufous-tailed rock thrush. It is at this time when the reproduction of these species reaches its peak and rocky cliffs are filled with different life and songs.
In July and August walks through valleys, fields and paramo will be the perfect complement to have spectacular days here. On the uplands, specifically cited in Torrano, - along with Dupont's lark, there are Black-eared wheatear, Greater short-toed lark, Tawny Pipit, Ortolan bunting, Spectacled warbler and Orphean warbler -it is also in juniper scrub- ...
On the banks of the río Pedro, we will have a choral symphony of many species of birds that will have arrived in those months: Common nightingales, Common chiffchaff, Robins, Spotted flycatcher, Golden orioles, Woodchat shrike and Red-backed shrike…
Chapter raptors have Montagu's harrier to the fields of Ligos and Torraño, Common buzzard and Booted eagle, furtive Eurasian sparrowhawk and the Short-toed eagle. Rarer hearing will be the Red-necked nightjar, detected in recent years in this area with the most abundant European nightjar. The Eurasian scops owl also they accompany our ears at that time because it is a common species in these banks still.
